That really isn't an ideal way to sew for me. I had the dress complete and then remembered that I was going to add something. I still could, I suppose. But, I won't. Because it feels done to me and I have a very hard time going back to fix something that feels finished. Silly, I know. But, it's the truth.
The dress is a very modified Kwik Sew 2918. The jersey is very stretchy in both directions, so I didn't have to add nearly as much length to the bodice as I anticipated I would. Ever since making this dress, I love to use clear elastic for gathering knits. The gathers are beautifully even and the seam remains stretchy.
The leggings are Burda 9615, made from a heather grey jersey knit that looks a little more athletic than I'd like, but I suspect my daughter will want to wear the dress without the leggings as the weather warms up more.
